' all 'zu/01:1 if; may concern.'

Be it known that I. JULIAN S. NOLAN, a citizen of the United States, residing at Highland Park, in the county ofl Lake and State oflllinois, have invented certain new and useful Improvements in Tile Structures for Reinforced-Concrete Floors, of which the followingl is a specilication. l

My invention relates to reinforced concrete floors of the type Iin-which the tiles are embeddcdin thetension zone of the floor for the purpose of lightening the structure 'and providing on the under side of it an all tile plastering surface or ceiling;

'and the invention has for its object to pron v provide a lcompletely closed hollow tileunit for use in concrete-and tile structures consisting of an open-ended, earthenware, tileV element and sheet metal closure plates forthe open ends ofthe tile element, together with suitable means for firmly binding the closure plates against the outer ends of the tile element.

The invent-ion is illustrated in certain typical cml'iodiments in the accompanying drawings, wherein Figure l is a plan view of a tile construction for a two-way reinforced floor, Fig. 2f

a sectional view taken on line 2)-2 of F ig. l,

looking in the direction of the a.i.1f n\fs,.ln1t' showing vthe concrete as well as 4the tiles;l

Fig. 3, a view similar to Fig. 2 taken on line 3 3 of Fig. l, looking in the direction of the arrows; Fig. Il, a view in perspective of a. preferred form of clip for binding the closure plates to the hollow t-ilc element; Fig. 5 asimilar view of another. form of clip. Fig. (i a fragmentary sectional view illustrating the application ofthe closure block and clip to the tile, Fig. 7 a plan view of a tilff'structure illustratinga moditied form of clip.l Figs. 'S and 9 a fragmentary sectional plan and a fragmentary vertical sectional view further illustrating this modification. F ig. 10 a view in per spective of the clip shown in the three preceding figures. F ig. l1 a plan view of a tile unit employing a modified form of closure block and clip for holding the same in place showing in sectional plan a portion of an' adjoining unit. Fig. l2 is a fragmentary vertical sectional view through a licor employing the unit shown in Fig. ll, and-Fig. i3 is a vieW,-in perspective, of the closure element employed in this construction. Like characters of reference indicate like parts in the several ti ur'es of the drawings. Referring first to igs l to 6 inclusive, 2() designates a number of hollow, openendecl, earthenwaretiles of ordinary form. .lhese hollow tiles arespaced apart by the flat tile elements 2l and 22, so that two sets of yintersecting channels are provided which -receive the reinforcing rods 23 and are iilled with the concrete 2a which makes up the body of the Hoor.. The open-ends ofthe hollow tiles are closed by sheet metallclosure plates 9.5 preferably formed at their upper edges with flanges 26 of the same width as. the plates which overlap the tiles.v The closure plates 25-are held firmly hound against the tiles so as to'prevent concrete from entering the same by means preferably of the wire clips 27 which extend over the top of the tiles and are formed-at each end with bends 28 which bear against'the plates 25. rlhe overlap of the langes 26 on the top of the tiles prevents any concrete from working into .the 'hollows of the tiles hetween the top of thetil'es and the closure plates. lThe flanges'v are particularly important because building 'tiles are scarcely ever perfectlyuiegular in forni. They are frequently warped 1 and often broken and irregular along the edges. The clips are somewhat bowed' and straightened out and pntl undo tension when applied. to the tiles.

In have'sliown a clip 29 of siinilar characterto.thatshown the preceding ligures, except that it is'niade of a .Strip of spring metal, instead of being made of wire.

Preferably' the closure plates L5 are formed at their lower edges with the outwai-diy projecting lianges 30 which. serve to sustain the flat spacing elements ll Under certain circumstances the, adhesion and 212.

between the concrete and the last-mentioned tile elements will be' suiiicicnt to make flanges 30 unnecessary.

fied construction. The closure plates 3l in l nml eoiiuiele nml provide, with snifl hollow clamped to the hollow tiles by means of the ll-shaped clips 33 (Figs, 8 and l0). Y

In the construction shown in Figs, 1l te 13 inclusive tlieelosure strips 34 are formell l with similar slits 35 and are secured to the hollow tiles by means of the Clips 3G. The hollow tiles might in :my of these eens-irmetions he llzuiged tiles S'o as to elo away with one set of 'the liet tile elements. In Figs. ll. and 12 the hollow tiles Q0il are formed en their closed Sides with flan ges 20".

1While have described my invention as embodied in certain typical constructions, it will loe realized that there might be Cei'- tein modifications made in the forms, coustrue'luions enel arrangements shown und described without departure from the inve1ition; therefore, l do not limit myself le tlieseperticulars except so far as they are mede specific limitations in. certain of the claims heiein.
